The invention is herein shown as embodied in a machine of the type disclosed in I Letters Patent of the United States No.

which is mounted in a pivoted head or lever,

the head or lever having imparted to it an angular movement proportional to the distance required between successive eyelets. It will be apparent that with this construction the path of the work feeding means is not rectilinear but curvedon a radius equal to the distance of the punch or setfrom the pivot of the head or lever in which it is mounted. In setting eyelets having a relatively close spacing the path of the feeding means departsso little from a straight line that no difficulty is experienced in properly guiding the work to setting position but, in setting large eyelets which are commonly spaced a considerable distance apart, the curved movement of the feeding means becomes objectionable and allows inaccuracies to occur in the feeding operation. With these conditions in view, it is an object of the present invention to provide mechanism for nnpartmg feeding movement in a rec-v tilinear path to a work engaging member mo inted for movement with a pivoted head. As herein shown, this result is secured by arranging the pivoted head or lever, or that part of the head or lever in which the work Specification of Letters Patent.

engaging member is mounted, so that it may ing means for controlling the path of its movement. One preferred form of guiding means comprises a. member having a guiding surface agalnst which runs a roller connected with the head which carries thesetting die. A spring actingupon the head through suitable connections serves to hold the roller in contact with said guiding surface and a cam, properly timed and oper ating through a cam lever and links, serves to swing the head about its pivot while its feeding portion is guided in a rectilinear path by the engagement of the roller with the guiding surface.

It will be apparent that with this construction a feeding movement of a very accurate character is insured and that its accuracy is unafiected by the extent of the feed ing movement or by variations in its extent. This characteristic is of much im- 1 portance and a valuable feature of the invention inasmuch as it is customary and necessary frequently to vary the extent of the feeding movement in machines of the class to which the present invention relates.

dies and the hopper which supplies said raceways is also supported on, and moved with, the oscillating raceway support. As is usual in such constructions, the hopper is provided with a rotatable agitator having a spindle projecting through the bottom of the hopper. Heretofore this agitator spindle has been turned by a flexible shaft "actuated from the main shaft of themachine. In accordance with the present invention it is proposed to eliminate from the machine the flexible driving shaft for the agitator and thereby improve and simplify its construction. As herein shown this is effected by providing a bearing bracket mounted adjacent to the axis ofthe agitator spindle so as to permit relative angular" movement between itself and the oscillating raceway bracket and arranging a rigid driv-- hopper with the raceway bracket.

a perspective view of parts of the actuating means for the agitator 1n disassembled relation; Fig. 6 is a sectional view of part of the head and one of the punches.

The illustrated machine, like that of said comprises oppositely disposed dies 12 arranged in bearings in the head 14 with the anvil or the die plate 16 also supported in said head and arranged between the oppositely disposed punches and setting dies. The anvil plate 16 carries a punching block 18 in alinement with the punches and an upsetting die 20 in alineinent with the setting dies 12. The head 14 is pivoted at its upper or rear end on a journal pin 22 carriedby the arm 24 of a bell crank lever pivoted to the frame of the machine on a pin 26. The other arm of the bell crank lever carr es a cam roller 28 which runs in a cam track 30. This cam operatesto shift. thehead forwardly and rearwardly as will appear hereinafter.

Transverse movement of the head 14 is In this way the operative connection betweenthe rigid shaft and the agitator splndle is preserved regardless of the movement of the.

efiected through the links id2and 34 and the "cam "lever 36 pivoted to the frame of the machine on a pin 38 and earryingcam roller which runs In the cam track 40. The feeding movement is effected-by the action of thecam lever 36 and to vary the extent of the feeding movement, and thereby the spacing of the eyelets mechanism is provided for varying the amount of trans- "verse movement transmitted through the v 7 ;links 32 and 34 to the head 14 from the cam Still another feature of the invention re lever 36. At the pivotalpoint of the links is secured another link 42 which is (pivoted uponan arm 44 movable over the face of a .quadrant plate 45, astop pin 46 being provided to limit its movement and a spring 47 $130 hold it in positionagainst the stop pin.

Thearm 44 is pivoted at its ree end to the quadrant plate 45 and it willbeseen that by iswingingthe arm towardethe right the piv- :otal point of the link 42 will be moved into :a position in which the link 42 will guide the pivot point of the'links 32 and 34 in an.

;are extending more ,orlessltransversely to the feeding movement ofthe head, a greater .component of the movement of the pivot :points of the links 32 and 34 becoming lost }motion as the arm 44 is moved farther toward theright.

The .punch andsetting dies are mounted in parallel hearings in the head 14 being :actuated by the cam lever 50 and retracted lby the levers '52 and 54 which are lifted'by the torsion springs 55. The 'head 14 is :moved forwardly or rearwardly to bring {either the punch or setting die under the ;endof the actuating lever 50 by the cam 30 acting through thebell crank lever 24 upon ithe head. Fig. l'shows the punch arranged in operative relation to the lever 50 and :those parts which are shown in Fig. 2 are in the same position.

A guide plate 56 andpresser foot 57 are mounted upon a fixed part of the machine frame and serve to guide the work as it is drawn into setting position by the transverse movement of the head 14. The cam 30, which actuates the bell crank lever 24, is constructed so as to move the head 14 .quickly toward the rear after the punching operation in order-to bring the setting dies 'into alinement with the previously punched holes. The cam is then widened, as shown in Fig. 4, so that it has no control on the forward and rear positionof the head. The cam 30 is so shaped that at-the completion of the transverse feeding movement it acts upon the roller 28 and the bell crank lever 24 to advance the head 14 forwardly,

this movement taking place during are-\ To the forward side of thefhead 14 issecur ed a bracket 60 upon which is journaled" which the roller 61 runs when the movement is taking place. The flange 63 is curved or inclined very slightly in order to compensate for pivotal movement of the head so that the set shall be moved in a The curvature required in straight path. the flange is indicated in Figs. 2 and 3 but is so slight as to be scarcely noticeable. It will be apparent that if the guideway. were absolutely straight the path of the feeding member of the machine would depart only very slightly from a straight line. Such construction would be satisfactory in many cases and is clearly within the scope of the invention. The guideway is hereinafter referred to as substantially rectilinear and this term should be construedto cover any guideway which will bring about a rectilinear or substantially rectilinear movement of the feeding device. The head 14 is held yieldingly toward the rear so that the roller 61 engages the guiding flange 63 by a tension spring 66 extending between an arm 67'on the rear end of the bell crank lever 2-1 and a lug on the frame of the machine. It will thus be seen that during the feeding movement of the work the path of the portion of the head 14 whichcarries the setting dies 12 is guided ina retilinear transverse path by the combined action of the guide flange 63, the spring 66 and the cam lever 36.. The initial position ofithe roller and head with respect to the guideway is shown in Fig. 2. In the first step in the cycle of operations the head is moved rearwardly and the roller carried into engagement with the guide flange 63, this position being indicated by dotted lines in Fig. 3. During the feeding movement the roller moves to the position indicated in fulllines and the setting die is guided in a substantially parallel path; In

the last step of the cycle the roller moves along a curved path from a positionshown in Fig. 3 to that shown in Fig. 2 under the combined influence of the cams 30 and 40.

The oscillatory raceway support 70 for the raceways 72 is pivoted to the machine frame at its left side, Fig. .1, and operated to swing the raceways to and from delivering position by the cam 74 acting through a cam lever 76 and a connecting link 78. The hopper 80 is carried-by the raceways and is located above the support 70. Within the hopper is disposed an agitator82, shown as a brush, having a finger 83 fast to its hub beneath the hopper bottom. Journaled on aspindle 85 set in the support 70 is a toothed disk 86 having an upstanding pin 84 arranged to engage the finger 83and turn the agitator when the disk 86 is rotated.

The disk 86 is rotated from the main shaft of the machine by the driving shaft '90 journaledat one end in the swivel bearing bracket 88 and at the other in the bearings 9% on the machine frame. The bearing bracket 88 is swiveled or pivoted upon the spindle 85 and has a bevel gear 92 which is held always, in mesh with the disk 86 re- Asfthe axes of the support 70 and the spindle 85 do not quite coincide it is apparent that there will be some bodily movement of the spindle 85 but since the bearing bracket is free to turn on the spindle its direction does not change and the shaft is never cramped. The outer end of the shaft is arranged to slide freely in the bearing 94 on the machine frame and is turned by a belt running over a pulley 95. The sliding movement of the shaft is never suflicient in extent to interfere with the driving connection of the pulley 95 and its corresponding pulley on the main shaft. The movement of the spindle 85 from front to rear and the resulting angular movement of the shaft 90 is provided for in the bearing 94 by making its bore slightly flaring.

The construction of the punches is best illustrated in Fig. 6 wherein the head 14 is shown as having a bore for the cylindrical body portion of the punch and a channel or keyway for a latch piece 99 secured to the body of the punch and arranged to hook over a shoulder formed on the detachable end portion, thus serving to hold the two portions together. Whenit is desired to re place the end portion of the punch, the punch isforced out of the head sufficiently to permit the latch piece to be lifted, whereupon the end its holder.
